The correct answer is: d) All of the above
Andhra Pradesh has witnessed a multi-party system with periods of dominance by the Indian National Congress, the Telugu Desam Party, and the YSR Congress Party.
The Indian National Congress (INC) was the first party to rule Andhra Pradesh after its formation in 1956. The INC ruled the state for most of the first 20 years of its existence, with the exception of a brief period in the early 1960s when the Praja Socialist Party (PSP) was in power.
The Telugu Desam Party (TDP) was formed in 1982 by N. T. Rama Rao, a popular actor and film producer. The TDP quickly became the dominant party in Andhra Pradesh, winning the 1983 state elections and forming the government. The TDP ruled the state for most of the next 10 years, with the exception of a brief period in the early 1990s when the INC was in power.
The YSR Congress Party (YSRCP) was formed in 2011 by Y. S. Jaganmohan Reddy, the son of former Chief Minister Y. S. Rajasekhara Reddy. The YSRCP won the 2019 state elections and formed the government.
The three parties have alternated in power in Andhra Pradesh over the years. The INC was the dominant party in the early years of the state’s existence, followed by the TDP and then the YSRCP. The state has witnessed a multi-party system with periods of dominance by each of the three major parties.
